Hello to all!
I am the new owner of the beautiful radio FR 6700. But I have one question for you.
Since I really like working in competitions in the SO2R category, I had the FT-1000 MP, TS-590, Microham u2r, and WX0B 2x6 pack in the previous configuration.
For easier control, switching antennas was done by PC via Microham and 2x6 switch.
Now I'm wondering if it's sensible or feasible to use Microham in combination with the Flex 6700, and 2x6 for automatic switching of antennas.
Thank you in advance for your reply.

    Try to get to know how to define USB cables by the Flex 6700. Each cable can be used as CAT, Band Data (BCD) or individual Bit cable.

    You will probably find that you can control most external switches. If you need more than two USB cables, use a USB hub.

    I am controlling an amp with two CAT ports and an antenna switch with 2x6 relays with the radio USB settings using four USB cables (FTDI type) and nothing else.

    @Erik SM0JCA is 100% correct.

    If you have a 6700, you are going to find that you will not require the Microham. SO2R command and OTRSP are actually built right into the radio. In fact you can sell it and buy a nice dinner. :)

    For your 2x6 switch, you can use the USB/Bit mapping on the back of the radio. Much much cleaner installation.
